1 Claim.

This invention relates to rail fastenings and is particularly intendedto fasten the rails of crane runways. In such instances the rails arespaced far apart and must, therefore, be carefully positioned as toself-alignment and to prevent parallax, one of the objects being toprovide a rela tively inexpensive but safe fastening while providing forlateral rail adjustments of suificient sensitivity to permit practicallyexact rail positioning.

Specific examples of rail fastenings embodying the principles of theinvention are illustrated by the accompanying drawing, in which:

Figure 1 is a side view of a first example with the rail and rail baseparts in cross-section.

Figure 2 is a top view of the above.

Figure 3 is a top view of a second example.

More specifically, in the first example the crane runway rail l issupported by an inverted channel 2 laid on a beam 3. A cam-plate 4 restson the channel 2 and a rail clip 5 is arranged on top of this plate, thelatter and the clip 5, channel 2 and beam 3 all having mutuallyregistering apertures so that a bolt 6 can be passed through all, a nutI being screwed on this bolt to cause the clip to press down on theplate and the top of the base of the rail.

The cam-plate 4 pivots on the bolt 6 and has a cam-edge l bearingagainst the adjacent side edge of the base of the rail I, and anoppositely extending part 4' by which it may be swung or turned when thenut 1 is sufliciently loose. The effect is then the desired lateralshifting of the rail I, it being understood that each installation willinvolve two sets of the described equipment so that shifting in eitherdirection is possible. Tightening of 5 the nut 1 looks the assemblyagainst further shifting.

Inthe case of the second example, the same parts are involved exceptthat a rectangular sliding cam-plate 8 is used instead of the pivoting10 plate 4. This plate 8 has a diagonal slot 8'' through which the bolt6 passes, and one of its straight side edges bears against the adjacentside edge of the base of the rail I. Sliding of this plate uponloosening of the nut 1 effects the action desired, duplicate sets being,of course, used with one set on each opposite, rail side, whiletightening of the nut effects the looking, as above described.

I claim: 20

A rail fastening comprising a rail base support, a cam-plate on saidsupport, a rail clip with one end on said plate and its other end on thetop of the base of a rail on said support, said support, said plate andsaid clip having mutually registering apertures, and a tension memberarranged through said apertures and engaging said I clip, said platepivoting on said member and having a cam-edge bearing on the side edgeof said base.
